The remake from mobile version of first-person shooter S.T.A.L.K.E.R. Mobile 3D! Action, railway type of game and mini-quests. The plot will be like the PC version of the same game, with known characters, heroes, objects and locations, but will not replicate it. The gameplay is like FPS with RPG elements, but you can controll actor only with mouse, just looking around. You can move just from point to point. Yes, this like old railway style of game.
